5-6-4-2. HUMI PID(Humidity)
Figure 5-6-10 HUMI PID
① HUMI REFERENCE
: Set the boundary value about humi span of PID zone.
② AUTO TUNING GROUP
: Go to the PID Group for PID(1~9) for change the PID value.
☞ Refer TEMP PID for detail function.
③ Tuning point : Set the range of value for starting or stopping MV when the Auto Tuning
☞ Ex) Range 0% ~ 100.0℃, TUNING POINT 1.0%, SV = 80.0% then
The meaning of TUNING POINT 1.0% is 1.0% for 100.0% (Full scale) so
the range will be 1.0%.
So if PV=81.0% then MV will be 0.0% and if PV=79.0% then MV will be 100.0%.
Both of OH, OL effect on both TEMP & HUMI when the AUTO TUNING.
☞ Ex) Auto Tuning can be doing only on Fix running, Auto Tuning is doing with SP and
the result will be saved automatically on the zone which is for SP.
